How to detect if a text is written by artificial intelligence

Artificial intelligence is one of the most disruptive technological revolutions in recent years. Specifically, the GPT Chat system, developed by Open AI, which issues responses with coherence and precision, is one of the leading trends that is on everyone's lips. While many admire its advanced functionality, others are more suspicious of the negative consequences that this tool can bring with it.

This is the case, for example, of the education sector. GPT Chat stands as a very useful tool for students when doing homework and assignments. This poses a problem for teachers to discern what the effort and learning of the students really is. Another case where it can be applied is in the writing of journalistic articles on the Internet, making it very difficult for readers to know if it is a text written by a reliable professional or by artificial intelligence.

Distinguishing them using only the particular criterion is very complicated. And it is that Chat GPT is so sophisticated that its writing style is very difficult to differentiate from that of a human. He uses expressions and set phrases, agrees tenses perfectly, builds complex and well-structured sentences, and even cites sources from which he obtains information. Any typographical error can be mistaken for a mistake, also frequent at the hands of a human being. For this reason, the best option to detect a text written by artificial intelligence is precisely to use it as an ally.

They say that if you can't beat the enemy, it's best to join him. This colloquial expression largely explains the popularity of Detect GPT, a tool that uses artificial intelligence precisely to detect when a text has been written by an AI. Although its nickname refers to GPT, the tool developed by Open AI, the truth is that Detect GPT can analyze texts executed by any generative artificial intelligence system.

Similar to how Chat GPT has been trained to generate language, Detect GPT uses logarithms within a linguistic model to calculate the percentage of text that has been rendered by an artificial intelligence.

This is a free extension available for Google Chrome that just needs to be downloaded to your browser. It does not require subscription, nor user registration nor any payment fee. Once downloaded, there are three possible ways to use it.

First of all, by accessing said extension and copying and pasting the text that you want the software to analyze. Another alternative is to pass it by hand. The third use that you can give it is directly from a web article, selecting the extension tab in Google Chrome and clicking on the 'refresh' button. Once the text in question has been analyzed, Detect GPR displays two estimated percentages, one relative to the probability that it was created by artificial intelligence and the other by a human.
